Every year, 2 million people converge on a small South Korean town for ten days of good clean fun, with 200 tons of mud and lots of alcohol.
Participants enjoy mud during the Boryeong Mud Festival at Daecheon Beach on July 12, 2008 in Boryeong City, South Korea. The annual mud festival, now in its 11th year, features mud wrestling, mud sliding and a mud king contest.

When the festival began, in 1997, its aim was to promote Boryeong's mineral-rich mud used in skincare and beauty products. Through most of the year, Boryeong City has less than 100,000 residents, but the population explodes when the festival begins.
The nine-day festival pumps an estimated $53 million into the local economy. (See more photos)
